SAWYER'S LOG MIRROR.

Application filed March 25, 1925.

My invention relates to a hand manipulated mirror having attachedthereto a light refiector adapted for use in saw mills and kindredplaces. This mirror is intended to reflect the end of the log oppositethe sawyer, in order that the sawyer may know the condition of the endof the log, before starting to saw the same. Devices of this kind areparticularly desirable where a log of large diameter is to be sawn, andwhere a log of great length. as well as large diameter is to be sawn. Anadjustable mirror is required, in order to reflect the condition of theend of the log to the sawyer. The Sawyer is located in a fixed position,at his post of duty.

An object of my invention consists in a frame support for the mirror anda means of manipulating the same.

A further object of my invention is to so support the mirror, that itwill have a tendency to hang or adjust itself into one primary position;and if other positions are required, to manipulate the mirror by handmanipulation and to mantain the same in desired position by a system ofcords or overhead tension members running over pulleys for that purpose.

Another object of my invention consists in providing a means ofconnecting and disconnecting the light projector, supported upon themirror frame, so that it will bear a fixed relationship to that of themirror.

A further object of my invention consists in so placing the .mirror thatit will reflect to the sawyer the condition of the end of the log,whether the same be of long or short length, without stopping thecarriage upon which the log is supported, at any particular locationwithin the range of the mirror.

With these and other objects in view, the invention consists in certainnovel features of construction and combination of parts, the essentialelements of which are set forth in the appended claim and to a preferredform of embodiment which is hereinafter described, and shown in thedrawings which accompany and form a part of this specification.

In the drawings- Fig. 1 is a front assembled view of the device shown inposition and mounted within the frame support.

Fig. 2 is a side elevation of the mechanism shown in Fig. 1, but upon alarger scale.

Fig. 3 is a cross-section view through the mill illustrating the logcarriage, the log Solial No. 18,211.

upon the carriage, a platform upon which the sawyer stands and apreferred eniibodiment of my device shown in position upon the framesupport adapted to reflect the condition of the end of the log structureto the sawyer upon the platform at the opposite end of the log carriage,and the manipulating cords for turning on and off the illuminatingsubsta co to be used in the projector, such as an electric light, and acord for manipulating the position of the mirror about its pivotalsupports.

Fig. 41 is a fragmentary, sectional view of the bracket support and thepivotal members adapted to support the mirror in position.

Like reference characters refer to like parts throughout the severalviews.

1 is the log carriage, 2 is the log in position upon the same, 3 is theplatform upon which the sawyer stands in directing the sawing operationof the log, 4 is the mirror frame having disposed therein a mirror 5.

The mirror for work of this kind should be substantial in construction,as of plate glass, and of large area in order that the same may beeasily seen under the conditions for which it is intended that the sameis to be used, and should be so arranged, in the mill, that thereflecting surface of the same may be easily accessible for keeping thesurface in a highly polished condition in order that it may reflect tothe sawyer true, exact and accurate conditions of the log end, oppositeto which the sawyer stands while directing the operations of sawing thelog; mirror brackets 6, are located at either side of the mirror frameand somewhat above the center of gravity thereof, having slots 7therein, and pivotally mounted as shown at 8 to the bracket support 9.Since the mirror is to be made of substantial area and of substantialweight, these supporting members should be of substantial proportion toadequately maintain the same in position and alignment. The centralpivotal support should be somewhat above the center of gravity of themirror in order that the same will have a tendencyto hang in a positionapproximating that of the vertical position. Disposed upon the onecentral edge of the mirror is an electric light and a reflector 10,having circuits 11 adapted to conduct electric energy therein forilluminating the same.

Under certain sawing conditions it may not be desirable to use thislight. I have, therefore, provided a cord 12, having its one endconnected to a suitable electric switch for turning on and off theelectric-energy required in illuminating the projector and having itsopposite end 13, disposed at a convenient location. for the operation ofthe same by the sawyer. I have a second cord 14, disposed upon one edgeof the mirror frame and having its opposite end terminating at 15, andin convenient location for manipulation of the saineby the sawyer; thereason for the required adjustment of the mirror is to compensate forthe different lengths of logs being; sawn, as it isapparent that theangle at which the reflecting mirror will be required to stand willdepend upon the location of the end of the log to be inspected by thesawyer, and it isrhighly desirable that the travel of the log; carriageshould be suflicient only to allow for the clearance of the saw beforethe logis set out for the next sawing operation and that the mirrorshould be located sufficient distance away from the sawyer to reflectthe condition. of the longest log to be sawn.

The pivotal support 16, for the mirr r frame, should have its one-endsupported in the support bracket '9, and its other end should passthrough the slot 7 of bracket 6,

and has the threaded nut 17, disposed upon its other-end to maintain thecollar 18, in working relationship with the bracket support in orderthat a true working [it may be securedbetween the supporting members andthe mirror.

While the form of mechanism herein shown and described is admirablyadapted ror, a frame therefor, slotted brackets fixed above the centerof gravity of said frame projecting rearwardly from opposite sidesthereof supporting means pivotally engaging said slotted brackets, andmeans associated with the frame and operable from a point remote fromthe mirror for tiltingthe mirror and maintaining it at the desiredangle.
